L' tude de l' rosion caus e par la boue est d'une importance cruciale pour diverses industries telles que le transport de particules abrasives, les syst mes de production dans les industries p troli res et gazi res, les machines hydrauliques, les pompes, l'industrie mini re, etc. Les d faillances caus es par l' rosion ont des cons quences n fastes et graves en termes de s curit et d' conomie. Les d faillances caus es par l' rosion ont des cons quences pr judiciables et graves en termes de s curit et d' conomie. La n cessit d'une dur e de vie durable est troitement li e la r duction des co ts d'entretien. Cela motive de nombreux laboratoires de recherche et industries effectuer des tests exp rimentaux sur l' rosion des boues. Il est donc n cessaire de disposer d'un mat riel d' tude de base qui puisse permettre aux tudiants, aux chercheurs en herbe et aux professionnels de fournir des directives d'essai pour les m thodes exp rimentales de l'usure de l' coulement de la boue.

Lo studio dell'erosione causata dall'usura di fondamentale importanza per diversi settori industriali, come il trasporto di particelle abrasive, i sistemi di produzione nell'industria petrolifera e del gas, le macchine idrauliche, le pompe, l'industria mineraria, ecc. I guasti causati dall'erosione comportano gravi problemi di sicurezza e conseguenze economiche. L'esigenza di una durata di servizio durevole molto legata alla riduzione dei costi di manutenzione. Ci motiva molti laboratori di ricerca e industrie a condurre test sperimentali sull'erosione dei liquami. quindi necessario disporre di un materiale di studio di base che consenta a studenti, ricercatori in erba e professionisti di fornire linee guida per i test sperimentali sull'usura del flusso di fango. Questo libro stato concepito dagli autori per servire a questo scopo fin dall'inizio.

Indie, pod względem produkcji i powierzchni, zajmują obecnie drugie miejsce wśr d kraj w uprawiających pszenicę na świecie. Calkowitą światową produkcję pszenicy szacuje się na 605,9 mln ton z 216,6 mln ha w latach 2005-2006, do czego przyczynilo się 11,4%. Siarka jest niezbędna do syntezy bialek, witamin i zawierających siarkę niezbędnych aminokwas w, a także jest związana z metabolizmem azotu. Siarka poprawia zar wno plony, jak i jakośc upraw. Niedob r siarki w glebie wzrasta wraz z intensyfikacją rolnictwa. Odmiany reagujące na nawozy przyspieszyly wyczerpywanie się siarki w glebie, nawet z mniejszej glębokości. Ciągle stosowanie nawoz w bez siarki spowodowalo powszechny niedob r siarki w glebach indyjskich i stalo się bardziej korzystne na glebach o lekkiej teksturze, kt re mają niską zawartośc materii organicznej. Informacje na temat wplywu siarki na plon, jakośc i pobieranie skladnik w odżywczych w uprawie pszenicy są ograniczone. Mając na uwadze powyższe fakty, niniejsze badanie zostalo przeprowadzone w celu zbadania wplywu poziom w siarki na wlaściwości fizykochemiczne gleby i wydajnośc pszenicy (Triticum aestivum L.).

Indien nimmt heute, gemessen an der Produktion und der Anbaufl che, den zweiten Platz unter den Weizenanbaul ndern der Welt ein. Die weltweite Weizenproduktion wird f r 2005-2006 auf 605,9 Millionen Tonnen auf 216,6 Millionen Hektar gesch tzt, was einem Anteil von 11,4% entspricht. Schwefel ist f r die Synthese von Proteinen, Vitaminen und schwefelhaltigen essentiellen Aminos uren unerl sslich und steht auch in Verbindung mit dem Stickstoffmetabolismus. Schwefel verbessert sowohl den Ertrag als auch die Qualit t von Kulturpflanzen. Der Schwefelmangel im Boden nimmt mit der Intensivierung der Landwirtschaft zu. Die auf D ngemittel reagierenden Sorten haben die Ersch pfung des Schwefelgehalts im Boden beschleunigt, auch in geringerer Bodentiefe. Der kontinuierliche Einsatz von schwefelfreien D ngemitteln hat zu einem weit verbreiteten Schwefelmangel in den indischen B den gef hrt und wirkt sich besonders positiv auf leicht strukturierte B den mit wenig organischer Substanz aus. Es liegen nur wenige Informationen ber die Auswirkungen von Schwefel auf den Ertrag, die Qualit t und die N hrstoffaufnahme von Weizenpflanzen vor. In Anbetracht dieser Tatsachen wurde die vorliegende Untersuchung durchgef hrt, um die Auswirkungen des Schwefelgehalts auf die physikalisch-chemischen Eigenschaften des Bodens und die Leistung von Weizen (Triticum aestivum L.) zu untersuchen.

As variedades responsivas aos fertilizantes aceleraram o esgotamento do enxofre no solo, mesmo a uma profundidade menor. O uso cont nuo de fertilizantes sem enxofre resultou numa defici ncia generalizada de enxofre nos solos indianos e tornou-se mais ben fico em solos de textura leve e com baixo teor de mat ria org nica.

L'India, in termini di produzione e di superficie, occupa oggi il secondo posto tra i Paesi produttori di grano del mondo. La produzione mondiale totale di grano stimata in 605,9 milioni di tonnellate da 216,6 milioni di ettari nel 2005-2006, con un contributo dell'11,4%. Lo zolfo essenziale per la sintesi di proteine, vitamine e aminoacidi essenziali contenenti zolfo ed anche associato al metabolismo dell'azoto. Lo zolfo migliora la resa e la qualit delle colture. La carenza di zolfo nel suolo aumenta con l'intensificazione dell'agricoltura. Le variet reattive dei fertilizzanti hanno accelerato l'esaurimento degli aumenti di zolfo nel suolo, anche a partire da profondit inferiori. L'uso continuo di fertilizzanti privi di zolfo ha portato a un'ampia diffusione della carenza di zolfo nei terreni indiani, che diventa pi vantaggiosa nei terreni a tessitura leggera e a basso contenuto di materia organica. Le informazioni sull'effetto dello zolfo sulla resa, sulla qualit e sull'assorbimento dei nutrienti nelle colture di grano sono limitate. Tenendo conto di questi fatti, la presente indagine stata condotta per studiare l'effetto dei livelli di zolfo sulle propriet fisico-chimiche del suolo e sul rendimento del grano (Triticum aestivum L.).

Reciprocity and Its Practice in Social Research

Reciprocity and Its Practice in Social Research

Igi Global

sidottu
Reciprocity has been critical in the philosophy and social sciences of the 20th century. Over the last seven decades, several countries settled by European powers have become autonomous, and returning has become a challenge. Consequently, writing on reciprocity as a central theme requires time and implies a deep dedication to the community. There is a need to explore the factors and policies behind the study agendas and secret philosophies before and after European involvement. Reciprocity and Its Practice in Social Research aims to open the controlled consciousness of self as a human being and then as a scholar to the community via the methodological lens. It analyzes reciprocity from the Greek tradition to Medeabale Arab to the early colonial or pre-colonial period. It specifically addresses the benefit of social research on the community and seeks ways to revolutionize and improve current research and academic processes. Covering topics such as the philosophy of science, indigenous science, and Western metaphysics, this book is an essential resource for anthropologists, philosophers, sociologists, university faculty and administration, students of higher education, librarians, researchers, and academicians.
